Did you read the entire article? He said the numbers were skewed because a large number of the 9mm shootings involved ball ammo. That would tend to make the 9 look less effective than it actually is because FMJ ammo is not a very good man stopper vs modern hollow point ammo. His data showed an average of 2.46 shots to incapacitate even with the FMJ shootings factored in. I have to ask myself how long it would take me to put 2.46 Gold Dots on target and the answer is not very long.
